This study aimed to investigate smoking cessation following the first two waves of the COVID-19 pandemic in Switzerland and to assess whether cessation differed according to participants\u2019 SARS-CoV-2\u2013related experiences. Data from S\u00e9rocoViD, a Swiss repeated cross-sectional study comprising five surveys in the canton of Vaud, was used. A total of 2454 participants aged 15 years and older from the first (May\u2013July 2020) and third (February 2021) surveys were included. Association between SARS-CoV-2 infection experiences and cigarette smoking cessation were analyzed using logistic regression; both factors were unadjusted and adjusted for age and gender. Overall, 21.2% of participants reported being ex-smokers, but only a small proportion of the entire study population (i.e., including both smokers and non-smokers) reported quitting during the pandemic (0.5% in the first sample, 1.5% in the second). Participants who were smokers before the pandemic and had undergone diagnostic testing for SARS-CoV-2 showed a trend toward smoking cessation during the pandemic (non-adjusted odds ratio = 2.15; 95% confidence interval: 0.79\u20135.87). No such trends were found with a positive diagnostic test or serological result, or with COVID-19-like symptoms. These findings suggest that individuals seeking testing may be more health-conscious, potentially contributing to smoking cessation. For these individuals, the pandemic may represent a critical opportunity to promote smoking cessation, which should be leveraged by healthcare professionals and public health policies.<\/jats:p>","DOI":"10.3390\/ijerph23020198","type":"journal-article","created":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T12:46:11Z","timestamp":1770122771000},"page":"198","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association Between SARS-CoV-2\u2013Related Experiences and Smoking Cessation in Switzerland: A Repeated Cross-Sectional Study"],"prefix":"10.3390","volume":"23","author":[{"given":"Elo\u00efse","family":"Cuvit","sequence":"first","affiliation":[{"name":"Department of Ambulatory Care, Center for Primary Care and Public Health (Unisant\u00e9), University of Lausanne, 1010 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9091-6703","authenticated-orcid":false,"given":"Margot","family":"Guth","sequence":"additional","affiliation":[{"name":"Department of Ambulatory Care, Center for Primary Care and Public Health (Unisant\u00e9), University of Lausanne, 1010 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5484-9016","authenticated-orcid":false,"given":"Semira","family":"Gonseth Nussl\u00e9","sequence":"additional","affiliation":[{"name":"Department of Ambulatory Care, Center for Primary Care and Public Health (Unisant\u00e9), University of Lausanne, 1010 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"D\u2019Acremont","sequence":"additional","affiliation":[{"name":"Global and Environmental Health Sector, Center for Primary Care and Public Health (Unisant\u00e9), University of Lausanne, 1010 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5281-0943","authenticated-orcid":false,"given":"Carole","family":"Clair","sequence":"additional","affiliation":[{"name":"Department of Ambulatory Care, Center for Primary Care and Public Health (Unisant\u00e9), University of Lausanne, 1010 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,3]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2024, September 11).
